TEXTILE-MACHINE.

T 0 aZZ whom it may concern Be it known that I, THOMAS Emvnsr BING- HAM, a subject of the King of England, residing at the city of Manchester, in the county of Lancaster, England, have in vented certain new and useful Improvements in Textile-Machines, of which the following is a specification.

This invention relates to machines for op erating upon warps, and refers particularly to a means for separating the threads of the warp or warps preparatory to subsequent operations, such as drawing-in or tying-in.

In the accompanying drawings, Figure 1 is a side elevational view illustrating two warps and a mechanism for operating upon said warps. Fig. 2 is a fragmental elevation of a carriage upon which said mechanism is supported, this view also illustrating the devices for actuating said mechanism and for advancing the carriage. Fig. 3 is a partial top plan view. Fig. 4 is a front elevation of the separating devices. Fig. 5 is a view, in the nature of a diagram, illustrating the operation of the separating devices. Fig. 6 is a detail view of one of the separating fingers. Fig. 7 represents a modified or alternative form of the separating device. Fig. 8 is a vertical sectional view of the carriage showing the knotter, and the carriage-moving and knotter-operating mechanism mounted thereon. Fig. 9 is a fragmental section along the line 9 9 of Fig. 8.

iVhile the invention may be embodied in various forms, the embodiment chosen to illustrate the invention comprises means for stationarily supporting the work and an operating mechanism arranged to travel transversely of the work.

The machine shown is adapted for use in tying-in warps.

The warps, the harnesses, and the reed may be supported in any suitable manner, as, for example, that illustrated in British Patent No. 1505 of 1910, or in a frame generally similar to that shown in United States Patent No. 955,383.

shown, is held in a clamp 1, the correspond ing end of the new warp Z) being secured in a similar clamp 2. The portions of the warps on which the mechanism operates are arranged in substantially parallel planes, the old warp being located above the new warp. Lease rods 3 supported in a suitable manner at a fixed distance apart extend through the warps so that the threads of each warp cross at a point t (Fig. The

mechanism for operating upon said warps is mounted upon a carriage 5 provided with wheels 6 arranged to roll upon rails 7 extending transversely of the warps. At the rear end of the carriage is fixed a standard 8 upon the upper end of which is mounted a thread-uniting mechanism 9. In this instance, the uniting mechanism is arranged to unite the thread by means of knots. Any suitable form of uniting mechanism may be employed, that herein shown being similar to the knotter illustrated in United States Patents Nos. 672,636 and 755,110. As incliated in the drawings, the uniting mechanism is supported adjacent to the horizontal planes of the warps.

The means for actuating the knotter may be of any suitable form. The means herein shown comprises a link 9 pivoted at its upper end to a crank arm 9 fixed to the actuating sector 9 of the knotter. The lower end of said link is pivotally connected to one arm of a lever 9 which lever is pivotally supported at 9 A spring 9 attached at one end to said lever and at its other end to a point upon the standard 8, tends to rock said lever in the direction to restore the knot-tying mechanism to its initial position. A suitable foot lever or treadle 10 is pivotally mounted upon a shaft 10 which shaft is carried in bearing brackets 10 fixed to the carriage. One end of the foot lever 10 underlies one end or" the lever 9 W hen the treadle is depressed by the operator the knotter 9 will be actuated to unite threads that may be presented to it, and when the operator releases the treadle the spring 9 restores the knotter to its initial position.

Fixed to the upper portion of the standard 8 is a bracket 11 carrying the mechanism for separating the threads of the warp. Fixed to said bracket is a post 12 in which two spindles 13 have a bearing. These spindles are arranged parallel to each other and extend toward and transversely of the warps in the vertical plane of the crossing points 4 of the threads. Upon the forward end of each spindle is fixed a suitable stop, such as a collar 14. Each of the spindles supports a separating finger 15 having a sleeve portion 16 which is slidable longitudinally of the spindle, but is held against turning movement with relation to the spindle by any suitable means, as, for example, a spline 17. A coiled spring 18 surrounding each spindle and interposed between the post 12 and the sleeve portion of the finger presses the finger against its warp. The spindles 13 are rocked to swing the separating fingers from one side to the other of the crossing points of the threads by any suitable means, as, for example, a plate 19 rigidly secured to a block 20 to which is fixed a guide stem 21 extending slidably through the post 12. Between the plate 19 and the adjacent side of the post 12 are crank disks 23 fixed upon the spindles 13, each crank disk carrying a pin 24 lying within a vertical slot 25 in the plate 19. It will be seen that when the plate 19 is horizontally reciprocated the spindles 13 will be rocked to swing the separating fingers 15 from side to side of the points 4.

The plate 19 is reciprocated by means comprising a cam wheel 26 and a ratchet wheel 27 rigidly connected together and ro tatably supported upon the post 8. Said cam operates upon rollers 28 carried by an arm 29, which arm is connected to the plate 19. Upon a block 30 fixed to the bracket 11 is a lug 31 to which is pivoted a finger 32. To the outer end of the finger 32 is pivoted a pawl 33 adapted to engage the teeth of the ratchet wheel 27. Said ratchet wheel, in this instance has twice as many teeth as there are points upon the cam wheel 26.

It will be seen that the finger 32 and the pawl 33 constitute a toggle. A spring 34 tends to swing the pawl 33 toward the finger 32. Said finger is swung by means herein shown as comprising a link 35 connected at its upper end with the pivotal joint between the finger 32 and the pawl 33, the lower end of said link being pivoted to a lever 36 pivoted in the framework upon the carriage 5, the opposite end of said lever overlying the end 10 of the foot lever. A. spring 37 attached at its lower end to the link 35 and at its upper end to the standard 8 restores the lever 36, link 35 and finger 32 when the operator removes his foot from the foot lever.

The shape of the separating finger 15 is best shown in Fig. 6 where it will be seen that the side of the finger which is presented to the threads is beveled as at 38. The tip of the finger is made somewhat pointed by reason of the beveled surfaces 39 40. The inclined rear face 41 of the finger assists to completely separate the released thread from its fellows.

Instead of employing a finger adapted to be oscillated back and forth over the point where the alternate threads in each sheet cross, I may employ a multifingered member, as illustrated at 42 in Fig. 7, and to impart to the same an intermittent or continuous rotary movement in but one direction.

The means herein shown for moving the carriage 5 so as to carry the thread-selecting and knot-tying mechanisms across the warps comprises a ratchet wheel 43 fixed upon the shaft 10, said shaft being connected by means of a gear train 44 with one of the axles of the carriage 5. A bell crank lever 45 is pivotally mounted upon the shaft 10 and carries upon one of its arms a pivoted pawl 46 adapted to engage the ratchet wheel 43, the other arm of said bell crank lever underlying a pin 47 fixed in the foot lever 10. A spring 48 tends to rock the bell crank lever in the direction to give the pawl 46 its restoring movement. It will be seen that when the operator depresses the treadle 10 the pawl and ratchet wheel will be actuated to traverse the carriage transversely of the warps.

In order that the feed movement of the carriage shall be proportional to the rate at which the tying of the warps progresses, I provide a two-arm lever 49 pivotally supported at 50 upon a bracket 51 fixed in the carriage. Said lever comprises an upwardly extending arm or feeler 52 arranged to lie in contact with the foremost thread of the lower or new warp. The other arm 53 of said lever is bent into hook form, as indicated in Figs. 2 and 9, to engage the pawlcarrying arm of the bell crank lever 45. The weight of the two-arm lever 49 is counterbalanced, and the feeler 53 is lightly held against the lower warp, by a spring 54. When the uniting mechanism is sufficiently near the warps the contact of the feeler 52 with the foremost thread of the lower warp holds the hooked end of the arm 53 behind the bell-crank lever 45 so as to limit the restoring movement of the pawl 46. When the restoring movement of the pawl is thus limited, depression of the foot treadle 10 is ineffective to advance the pawl far enough. to turn the ratchet wheel 43. As the threads are withdrawn from the warp and united, the feeler 52 swings in the direction to maintain contact with the lower warp, and, in so doing, the hooked end of the arm 53 is withdrawn from engagement with the bell crank lever 45; whereupon the spring 48 is free to give the pawl 46 a complete restoring movement. The next depression of the treadle will cause the pawl to rotate the ratchet wheel 43 and thus feed the uniting mechanism toward the warps.

In use the carriage 5 is advanced until the separating fingers 15 press against the end threads of the two warps, so as to give the threads a slight lateral deflection, it being understood that the warps are under longitudinal tension. Actuation of the foot lever will cause the fingers 15 to swing back and forth across the points at, each movement of a finger causing the release of a thread.

If 0 (Fig. 5) be assumed to be the end thread of the upper warp, movement of the finger from the full-line position to the dotted-line position will relieve the thread 0 of the pressure of the finger, and said thread will immediately spring behind the finger as indicated in Fig. 4 whereby the thread 0 is separated from the remainder of the threads. Return movement of the finger may assist to move the thread 0 still farther from its fellows. As pairs of threads are thus separated from the warps, the operator places the pair in the knotter 9, where they are united.

The fingers 15 may be supported at any side of the crossing points 1, so long as each is arranged to engage alternately the two sheds or sheets formed by the leasing of the warp.

It will be seen that the separator fingers are yieldingly mounted, so that each may accommodate itself to the position of itswarp threads; in other words, it is not necessary that the end threads be vertically alined, or one immediately above the other.
